Method for data interaction of aircraft whole avionics equipment

Abstract

The present invention provides a method for the data interaction of aircraft whole avionics equipment. In order to collect complete data of the aircraft whole avionics equipment, a cable plug end connected to a flight parameter recording device is used as an interface of the data interaction, test equipment is connected, signals of a bus, a discrete amount, a switch quantity and the like are collected in real time, and at the same time, corresponding bus data can be inputted via a simulation stimulus function of the test equipment. Through an above data interaction mode, the purpose of closed-loop online detection is achieved. The collected data of original aircraft avionics equipment does not need to be transferred and processed, and the integrity and reliability of the data are ensured.

Description

technical field [0001] This patent relates to the technical field of on-line testing of aircraft avionics equipment, in particular to a method for data interaction of aircraft avionics equipment. Background technique [0002] The avionics equipment of the aircraft is mainly divided into avionics system, flight control system, power supply, electromechanical system, etc. During the assembly process of the aircraft, the function and performance of the avionics equipment must be tested to ensure the quality of the aircraft and flight safety. [0003] At present, before the whole machine is assembled, the avionics equipment adopts the method of testing the components or systems in the laboratory, and then the whole machine is assembled after the test is completed; Simple function check of the control functions. In actual work, only the method of decomposing the original avionics or its connecting cables can be used to change the avionics system of the whole machine from a close...

AI Technical Summary

Problems solved by technology

For example, when testing an in-situ test equipment, it is necessary to disconnect the original cable and connect the test equipment cable to the on-board equipment for testing. Originality, low reliability, can only be used as a means of fault diagnosis, and cannot be applied to the production assembly process

To sum up the above, the problems existing in the existing technology mainly lie in 1. On the premise of not disassembling the original avionics equipment and its connecting cables, it is impossible to collect the online data of the whole machine, and it is also impossible to input external commands or simulation incentives, resulting in online testing. The content is incomplete and cannot achieve the purpose of closed-loop detection of the aircraft avionics system

2. Some aircraft can collect data through the detection port of the flight parameter recording equipment, but the data cannot be collected after the processing of the flight parameter recording equipment.

3. It can only be stimulated by sensors, and cannot realize bus excitation simulation and verification of more functions
